This isn't some surreal work of art or alien structure – it's a tent! The Tentsile, a portable suspended tent (Tent? Treehouse? Hammock?) created by UK-based inventor Alex Shirley-Smith, solves the problem of setting up camp on rocky, muddy, or otherwise unpleasant surfaces by hanging from the trees. The Tentsile was envisioned by Shirley-Smith in 2010, and the first production model was launched in early 2013.
